INKSTAND.

Specification of Letters Patent.

Patented Jan. 30. 1906.

Application June 3, 1905- sell flll NO- 263608.

To LtZZ whom it may concern:

Be it known that I, ERNEST J. Oseoon, a citizen of the United. States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Inkstands, of which the following is a specification.

Myi nvention relates to ink-wells, more particularly to that class wherein the ink is contained in a reservoirand fed to a well by the compression of a bulb.

The primary object of my invention is to provide a tube adapted to convey or feed the ink from the reservoir to the well and which is provided with a passage restricted at its lower end and gradually increasing in diameter upwardly, whereby to prevent too great a quantity of ink entering the tube and spurting out of and over the well.

A further object of the invention is to adjustably mount the tube whereby it may be moved to project its lower end into the ink in the reservoir to insure the perfect working of the device no matter what quantity of ink the reservoir contains.

A still further object is to provide means adapted to perform the dual function of holdingthe tube in its adjusted position and preventingthe pen-point from being injured upon insertion into the well.

The invention consists in the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illus trated in the accompanying drawings, which disclose the preferred form of my invention, and in which" Figure 1 is a vertical central sectional view of an ink-well constructed in accordance with my invention, and Fig. 2 is a top plan view thereof.

Referring to the drawings by reference-um morals, 1 designates a reservoir fully open at its-upper end and of a design and capacity that will best adapt it for the purpose for which it is designed. The inner face of the verticalwall of the reservoir is cut away to provide a shoulder 2, upon which is adapted to rest a cover 3. This cover may be secured in applied position by means of cement or fusion and is designed to hermetically seal the reservoir. The cover is provided with an opening 4, adapted to receive a well 5, which is provided with a shoulder 6, adapted to rest upon the upper face of the cover to suspend the lower end of the well 5 Within the reservoir. The well 5 is also adapted to be secured in applied position, so as to seal the opening 4. The cover is provided with another opening 7, which is adapted to receive the reduced end 8 of a plug 9, which is removably secured in applied position; The plug is provided with an opening 10, extending vertically throughout the entire length thereof, and whereby communication is established. between the interior of the reservoir and the outer atmosphere. Mounted upon the plug 9 and suitably secured thereto is a compressor 11, which is provided with an opening 12, situated within the upper end thereof. This compressor is adapted to be manipulated so as to cause a pressure within the interior of the reservoir to feed the ink into the well 5 in a manner that is apparent. After the air has been exhausted from the compressor 11 and the operator has removed his finger from over the opening 12, which is placed thereon duringthe manipulation. of the compressor, the pressure within the reservoir is relieved, as is apparent. The plug 9 mpy be removed to supply the reservoir with 1n A tube 13 is carried by the well 5 and has its lower end projected into the ink within the reservoir, whereby the ink is conveyed into said well upon the manipulation of said compressor. This tube is provided with a passage restricted at its lower end and gradually increasing in diameter upwardly, whereby all liability of too great a quantity of fluid being forced into the tube and spurting out of and over the well is obviated.

All portions of this device, except the compressor 11 and tube 13, are constructed of glass, and in order to prevent the pen from being injured upon insertion into the well 5 and to secure the tube 13 in position I mount within the well 5 a rubber protector 14. This protector is disk-shaped and provided with an opening adapted to snugly receive that portion of the tube situated. within the well 5.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described the invention, what is claimed as new is 1. In a device of the character set forth, a reservoir, a well having connection therewith, a compressor mounted on the reservoir, a feed-tube adjustably carried by the well and having its lower end projecting into the reservoir, and a protector situated within the well and adapted to support the tube in adjusted position.

2. In a device of the character set forth, a

reservoir, a well having connection therewith, a compressor mounted on the reservoir, a feed-tube adjustably carried by the well and having its lower end projecting into the reservoir, said tube being provided with a passage restricted at its lower end and gradually increasing upwardly, and a protector situated within the well and adapted to retain the said tube in its adjusted position.
